Is it possible to automatically invoke a given applescript when closing -any- file with a given extension in a specified folder (and subfolders)?

If not in AS, is this possible in bash? (The AS I am considering simply calls a bash script.)

If the script could also be run when you open a file (or in other cases), you could use opensnoop.



while :; do
    opensnoop | grep -Ev ' (mdworker|mds|filecoordinatio|revisiond|Finder|Alfred) ' | grep -m1 '/Users/username/Folder/.*\.txt'
    say a
    sleep 1


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC -//Apple Computer//DTD PLIST 1.0//EN http://www.apple.com/DTDs/PropertyList-1.0.dtd>
<plist version="1.0">

chmod +x ~/test, sudo chown root /Library/LaunchAgents/test.plist, and launchctl load /Library/LaunchAgents/test.plist.

  • Thanks -- but unfortunately, this script is only to be run on file close.
